SPECIFICATION formingvpart oflnetters patent No. 677,764, dated July' e, 1901. Application filed October y143'1900l 'Serial No. 32,955. (No model.)

To LZZ whom, t may corr/cern.-V

Be it known that I, ALFRED M. HEwLii'rr,v a citizen of the United States, residing at Ke# wanee, in the county of'Henry and 'State of Illinois, have invented certain new and use` ful Improvements in Heating Apparatus, of which the following is a specification, refe r. ence being had to the accompanying drawings. i

My invention relates to heating apparatus,

and has reference particularly to appliancesused in steam and hot-water heating systems. In such systems it is customary to 'employ radiators made up of a number` of separate sections ixedly united together to form aradiator, through which the steam 'or water is conducted. The sections are usually oblong or elliptical in 'cross-section andiare afterposed, making it impossible to decorate themA to any considerable extent, as well as retarding radiation.

The object of myinvention is to provide an improved radiator the sections of which are coupled together in such manner as tol present their broad surfaces outermost, making it possible to. secure better decorative effects as well as improved'radiation; also, to provide a radiator composed of sections oblong in cross-section, certain sections being angularly arranged with reference to other sections and all being united by external coupling devices placed between each pair of sections.

In the accompanying drawings, Figure 1 is a perspective view of one of myimproved radiators'. Fig. 2is a horizontal section on line 2 2 of Fig. 3. Fig. 3y is a longitudinal verticalsection of a steam-radiator. Fig. 4 is a longitudinal vertical section of a hot-water radiator. Fig. 5 is a `plan view of an end ,section`y and several intermediate sections, ishowing the coupling devices. Fig. 6 is an enlarged horizontal section of several radia-Y tor-sections, showing the couplingdevices. Fig. 7 .is an enlarged sectional view showing ,the coupling uniting one of the lend sections with the hot-water or stea'm pipe. i Figs. 8

and 9 are sectional views 'showing details of l the coupling devices. Fig.AV 10 is an elevation of thesame, and Fig. 11 is a section on line 13 13 of Fig. 2.

Referringto the drawings, 15 16 indicate the end sectionsof aradiator, of which 17 indicates the intermediate sections. In the radiatorillustrated in Fig. V1 ther end sections `are parallel with each other, the intermediate sections being arrangedgat right angles to the end sections and parallel with the other intermediate sections. Each of the sections is in the form of an oblong square, and by the arrangement illust-rated a radiator is formed the sides and ends'ofwhich' present broad surfaces, sothat they aord ampleopportunity for decorative effects and valso are more exposed, so that radiation is facilitated. The "end sections are provided with legs 18, which support the radiator as a whole. The arrangement of the connecting devices by which the sections are united is best illustrated in Fig. 2, from an inspection of which it will be noted that the intermediate sections are connected together and to the end sections by a series of projecting stubs or pipes, the stubs of adjacent sections abutting andbeing rmly clamped together, so that free communication is afforded between the different sections composing the radiator.

' 'Inthe radiator illustrated in Figs. 1 and 3 there are three rows of intermediate sections, each extending longitudinally of the radiator and each row being composed of three sections. For convenience of reference the sections will be indicated by reference-letters A B C, respectively. Transverse rows are formed by the sections in each of the longitudinal rows A B C, and the connecting devices which connect the different rows are arranged transversely of the radiator, as shown in Fig. 2. For example, each section 17 in the row A is provided with a projecting stub 19- on its in ner side near its lower end, which IOO is arranged to abut against a similar stub 20, projecting from the face of the opposite section in row B, and said stubs are closely clamped together by a binding device, which Will be hereinafter described. The same arrangement is found at the opposite side of the radiator, and the sections in each of the transverse rows are similarly connected together.

The end sections l5 16 are connected with all the other 'sections by means of the intermediate row B, and the sections of the row B are connected in a series in a similar manner-that is t-o say, each of the end sections 15 16 is provided with a projecting stub 21, which abut-s against avstub 22, which projects from one edge of one of the sections in the intermediate row B, as shown in Fig. 2, said stubs being clamped together by appropriate clamping devices, as will be hereinafter described. Vhere two sections of the intermediate ro-w B are clamped together, their stubs 22 abut, as also shown in Fig. 2, and are similarly clamped together. It will be seen,

therefore, that by the construction described the hot water or steam in the end section 15 may pass into the section of the intermediate row B, which is connected thereto, and may thence flow into the remaining sections of the intermediate row, as well as into the sections in the rows A and C.

vWhere the radiator is designed for steam heating, the sections are not connected at their upper ends, but are provided with the usual lugs 23 to hold them apart, as shown in Fig. 3. Vhere the radiator is intended for hotwater heating, connecting-stubs similar to those already described are provided at the upper ends of the sections, as illustrated inv The clamping devices by which the Fig. 4. stubs are connected are best shown in Figs. 5 to 11. They consist of a collar 24, adapted to t upon the abutting ends of the stubs carried by the sections, said collar being provided on its inner face with lugs 25 26, two pairs of said lugs being preferably provided. The lugs 25 are placed nearV one end of the collar 24, while the lugs 26 are placed near the opposite end, and both of said lugs arev slightly tapered on their surfaces which lie farthest from the ends of the collar, as shown in Fig. 8. The lugs 25 26 are oppositely inclined, so that they operate alike on their respective stubs. Each stub is provided near its end on its outer surface with a lug 27, as shown in Fig. 8. The collar 24 when turned to bring its lugs 25 26 between the lugs 27 of one of the stubs 22 may be slipped upon said stub and may then be turned to carry its lug 25 or 26 back of the lug 27 of the stub, as illustrated in Fig. 6, and when the stubs of two sections are brought together within the collar 24 by turning the collar to carry its lugs 25 26 back of the lugs 27, carried by the stubs, the inclined surfaces of said lugs 25 26 act as wedges to force the abutting faces of the stubs tightly into contact with each other ermee and bind them rmly in such position. The inclination of the lugs 25 2G is slight to increase their power and prevent liability to slip. The collars 24, which unite the differ ent sections, being mounted externally upon the stubs, are exposed and are readily accessible, so that the parts of the radiator may be readily assembled or separated. In assembling the parts all that it is necessary to do is to bring the stubs of the sections to be united together within one of the collars 24, the collar being turned to proper position to permit such assembling, when by turning the collar Y about ninety degrees the stubs are tightly forced together and a continuous coupling provided. Inasmuch as to separate the sections it is not necessary to insert a tool into the sections, the stubs may be located at any desired points on the sections and couplings may be made at such points, and it is therefore possible to build up radiators of any desired shape or style.

In practice the inner portions of the stubs 22 are enlarged, as shown at 28 in Fig. 7, and are provided with a projecting rim 29, which projects over the adjacent end of the collar 24, thus inclosing the end of the collar and providing a neater as well as a more secure construction. The enlargement 2S is usually provided where the stubs project from the edges of a radiator-section, as illustrated in Fig. 7. Vhere'they project from one of the side faces, av rim or flange 30 only is provided, as shown at the left'in Fig. 7, the eect being the same, as the surface of the radiator-sections servesin lieu of the enlargement 28.

It will be'understood that the transverse rows of radiator-sections may be composed of two or more sections.

That which Iclaim as my invention, and desire to secure by Letters Patent, is-

1. A radiator consisting of a plurality of separable end and intermediate sections having one dimension in cross section longer than the other, the intermediate sections being arranged in transverse rows and disposed augularly with reference to the end sections so that the side portions of the radiator are formed by the broad outer surfaces of the sections at the ends of the transverse rows, and couplings connecting said sections, substantially as described. Y

2. A radiator consisting of a plurality of communicating end and intermediate radiator-sections, the intermediate sections being arranged in transverse rows, the length of said rows being substantially equal to the width of said end sections and coupling devices connecting said sections, substantially as described.

3. A radiator consisting of a plurality of communicatin g end and intermediate radiator-sections having one dimension. in vcrosssection longer than theY othergthe intermediate sections being arranged'inv transverse rows, the side portions ofthe radiator being IOO formed by the broad outer surfaces of the sections at the ends of the transverse rows, th-e length of said rows being substantially equal to the width of the end sections, and coupling devices connecting said sections, substantially as described.

4. A radiator consisting of a plurality of separable end and intermediate sections, the intermediate sections being arraugedin transverse rows, the length of said rows being substantially equal to the width of said end sections, each of said sections havinga .projecting stub or stubs, the stubs of the different sections being arranged to abut to forni pipes between adjacent sections, and an external rotatablecollar ttin g over the abutting ends of each pair of stubs, said collars having lugs adapted to engage corresponding lugs carried ried by said sections and overlapping the 3o ends of said collar, substantially as described.
